8 - Troubleshooting & Maintenance
When a fault occurs, the cause must be corrected before the fault can be cleared. If the protective
function stays active, it could lead to a reduction in product life and damage to the equipment.

Protective Function Description
Overcurrent
The drive turns off its output when the output current
of the drive flows more than 200% of the drive rated
current.
Ground fault current
The drive turns off its output when a ground fault
occurs and the ground fault current is more than the
internal setting value of the drive.
Inverter Overload
The drive turns off its output when the output current
of the drive flows more than the rated level (150% for
1 minute).
Overload trip
The drive turns off its output if the output current of
the drive flows at 150% of the drive rated current for
more than the current limit time (1 min.).
drive Overheat
The drive turns off its output if the heatsink overheats
due to a damaged cooling fan or an alien substance in
the cooling fan by detecting the temperature of the
heatsink.
Output Phase loss
The drive turns off its output when the one or more of
the output (U, V, W) phase is open. The drive detects
the output current to check the phase loss of the
output.
Over Voltage
The drive turns off its output if the DC voltage of the
main circuit increases higher than 400 V when the
motor decelerates. This fault can also occur due to a
surge voltage generated at the power supply system.
Low Voltage
The drive turns off its output if the DC voltage is
below 180V because insufficient torque or overheating
of the motor can occur when the input voltage of the
drive drops.
Electronic Thermal
The internal electronic thermal of the drive determines
the overheating of the motor. If the motor is
overloaded, the drive turns off the output. The drive
cannot protect the motor when driving a motor having
more than 4 poles or multi motors.
Input Phase Loss
Drive output is blocked when one of R, S, T is open or
the electrolytic capacitor needs to be replaced.
Self-diagnostic
malfunction
Displayed when IGBT damage, output phase short,
output phase ground fault or output phase open occurs.
